//=================================================================

// Implementation of a menu deskbar object that uses TrackPopupMenu.
|
|
//
|
|
// This object uses traditional USER32 menus (via TrackPopupMenu)
|
|
// to implement menu behavior. It uses the CMenuAgent object to
|
|
// help get its work done. Since the menu deskbar site (_punkSite)
|
|
// sits in a modal loop while any menu is up, it needs to know when
|
|
// to quit its loop. The child object accomplishes this by sending
|
|
// an OnSelect(MPOS_FULLCANCEL).
|
|
//
|
|
// The only time that TrackPopupMenu returns (but we don't want to
|
|
// send an MPOS_FULLCANCEL) is if it's b/c the Escape key was hit.
|
|
// This just means cancel the current level. Returning from Popup
|
|
// is sufficient for this case. Otherwise, all other cases of
|
|
// returning from TrackPopupMenu means we send a MPOS_FULLCANCEL.
|
|
//
|
|
// Summary:
|
|
//
|
|
// 1) User clicked outside the menu. This is a full cancel.
|
|
// 2) User hit the Alt key. This is a full cancel.
|
|
// 3) User hit the Esc key. This just cancels the current level.
|
|
// (TrackPopupMenu handles this fine. No notification needs
|
|
// to be sent b/c we want the top-level menu to stay in its
|
|
// modal loop.)
|
|
// 4) User selected a menu item. This is a full cancel.
